AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability affects OpenClaw, a personal AI assistant. Before version 2026.2.14, OpenClaw's Server-Side Request Forgery (SSRF) protection could be bypassed by using full-form IPv4-mapped IPv6 literals, such as '0:0:0:0:0:ffff:7f00:1', which corresponds to the IPv4 loopback address 127.0.0.1. This bypass allowed requests that should have been blockedβsuch as those targeting loopback, private network, or link-local metadata addressesβto pass through the SSRF protection.
How can this vulnerability impact me? :
This vulnerability can allow an attacker to bypass SSRF protections and send unauthorized requests to internal or sensitive network addresses that should normally be blocked. This could lead to unauthorized access to internal services or metadata endpoints, potentially exposing sensitive information or enabling further attacks within the internal network.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
